I am trying to move my combined BE/FE to a new location and using TV out from my ATI video card. I am using SVIDEO output to the TV. The boot sequence displays ok but when it changes to X the output changes to unintelligible as if the frequency is wrong. The TV format is PAL-B (Australia). If I control the system using VLC I can initiate Watch TV and the TV display seems to change. The sound is at this time is OK
I have edited xorg.conf in accordance with
http://www.knoppmythwiki.org/index.php? ... Transition
The fragment from xorg.conf is
Section "Screen"
Identifier "Screen0"
Option "TVStandard" "PAL-B"
Device "Card0"
Monitor "Monitor0"
DefaultColorDepth 16
SubSection "Display"

Any ideas or help appreciated

Sounds similar to this post. Perhaps one of the suggestions there will help you out...

Whilst I don't have a direct answer, I think your res may be too high at 1024x768 some TVs can't handle that, so when you watch TV it is only 720x576.

Here are a couple of links that may be useful:

Hope that helps. If you are in Brisbane I would be happy to call and help you out.

You might try removing all the "1024x768"'s from the lines beginning with
'Modes'. The second problem is that these resolutions and other lines
may need to be tweaked for non-US resolutions/frequencies.

By the way, you should do your install starting by entering 'tv' at the
'boot:' prompt on the KnoppMyth install CD. That tells it that these high
resolutions are a no-no.

Thanks for your input. My xorg.conf now looks like this but unfortunately it is still showing scrambled output. I don't really want to re-install when I am not sure it will help.

I moved the TVStandard to the device section based on some input on one of the links. Any thoughts

First off: Playing with timing values has been known to
actually fry TV's and monitors. I give this advice in good
faith, but I have not tested it myself and don't have full
knowledge of your hardware, so don't blame me if your
TV or monitor fries...

There is a thing called a 'modeline' that can be
put in xorg.conf that is probably a quick fix if you can find
the right one. This mode line tells it exactly what the timing
should be and overrides the default values that don't seem to
be working for you. I would google it or search the forums
here. There should be one to find as it is a standard PAL-B
TV set.

Here is what I found at: http://www.mythtv.org/wiki/index.php/Modeline_Database#PAL_625



Take this whole chunk and put it in your 'Monitor' section,
then try the resolution on each of your 'Modes' lines with
one of the values from each Modeline. You will change
all of your: with: for instance. I would try the first
and last modelines from the looks of it.

I hear that the stock (no modeline needed) "800x600" mode
works well, even for PAL. I use it on my NTSC setups too.
Did you ever try that as it is what you would have tried if
you had just removed the "1024x768".

If you have an old 6+ gig hard drive you might try installing
a clean R5F27 on it to get some ideas like a new xorg.conf.
If you don't have an old hd, you might be able to back up
just your root partition (< 5 gig) onto a DVD or your /myth
partition (since you undoubtedly have more than 5 gig free
there), doing a test install using 'tv' (!! 'upgrade install' to
avoid wiping out your data!!) and restoring from the DVD
or /myth backup later.

Good luck,
Cliff

Instead of a reinstall you could try an upgrade, the only problem being you would need to do a backup first. That being the case you would probably best connect a monitor to do the backup and then disconnect it to do the upgrade, remembering to put 'TV' at the boot prompt.
